Slide knob mounting structure

Abstract

A structure for mounting a slide knob included in, e.g., a portable apparatus is disclosed. The structure of the present invention allows a slide knob to be mounted to the apparatus without resorting to screws and therefore reduces the number of assembling steps and the number of parts.

What is claimed is: 
     
       1. A slide knob structure in which a knob of an electronic part is mounted on a circuit board within a casing, said knob being slidable in opposite directions via a thumb piece protruding from a window formed in said casing, said slide knob structure comprising: a slide knob including a rectangular plate, the thumb piece being formed on one major surface of said plate and protruding from the window, and a pair of lugs formed on the other major surface of said plate;   a pair of bearing members affixed to an inside of the casing at both sides of the window and each having a rectangular hole, said slide knob being positioned between said pair of bearing members in a preselected position; and   a stop including a pair of parallel arms each having a respective locking end;   wherein said stop is inserted into the holes of said pair of bearing members with the locking ends of said pair of arms at the head in such a manner as to press said slide knob, whereby said locking ends prevent said slide knob from slipping out while said pair of arms allow said slide knob to slide.   
     
     
       2. A structure as claimed in claim 1, wherein said stop comprises an elastic molding. 
     
     
       3. A slide knob structure in which a knob of an electronic part is mounted on a circuit board within a casing, said knob being slidable in opposite directions via a thumb piece protruding from a window formed in said casing, said slide knob structure comprising: a slide knob including a rectangular plate, the thumb piece being formed on one major surface of said plate and protruding from the window, and a pair of lugs formed on the other major surface of said plate;   a first and second pair of parallel arms respectively extending out from opposite ends of said plate, said arms each including a respective locking end; and   a pair of bearing members affixed to an inside of the casing at both sides of the window and each having a rectangular hole;   wherein after the locking ends of either one of said first and second pairs of arms have been inserted into the hole of one of said pair of bearing members, the locking ends of the other pair of arms are inserted into the hole of the other bearing member while being elastically deformed with said thumb piece protruding to an outside via the window, whereby said slide knob is allowed to slide while being prevented from slipping out by said locking ends.   
     
     
       4. A structure as claimed in claim 3, wherein said slide knob and said first and second pairs of arms are implemented as a single molding.
